ABSTRACT:
A toner for developing electrostatic images is provided. THF-soluble matter of the toner has, in molecular-weight distribution as measured by GPC, at least one peak in the molecular weight region of from 1,000 to less than 2,000 and at least one peak in the molecular weight region of from 2,000 to 300,000, and has a weight average molecular weight of from 90,000 to 2,000,000. Molecular weight integral value T in the molecular weight region of 800 or more, molecular weight integral value L in the molecular weight region of from 2,000 to 5,000 and molecular weight integral value H in the molecular weight region of 300,000 or more satisfy the relationship :
